Extract from Wikipedia article: Coprinopsis acuminata, commonly known as the humpback inkcap mushroom and earlier as Coprinus acuminatus, is a coprophilous fungus that grows on herbivore dung. It is heterothallic.
Coprinopsis acuminata is a species of fungus that belongs to the family Psathyrellaceae. It is characterized by its small to medium-sized fruiting bodies, typically 1-4 cm tall, with a bell-shaped to conical cap that is often umbilicate and ranges in color from brown to grey-brown. The gills are crowded, free, and turn black as the spores mature. In St. Petersburg, Leningrad Oblast, and north-western Russia, Coprinopsis acuminata has been found growing on various substrates, including soil, decaying wood, and plant debris, often in association with coniferous and deciduous trees. It typically fruits from summer to autumn, particularly in moist, shaded areas. The species is considered widespread but not abundant in the region, with sporadic records from urban parks, forests, and grasslands.
